NetBeans制成的jar文件无法通过双击启动

Question

I know this problem has been discussed many times here. I am running on MAC with OSX 10.7.4 and NetBeans 7.2.1

I don't know if this is a new wrinkle or not, I'm a java newbie. In any event with my project selected in the projects window it shows the project:

Idealizer -> Source Packages -> components-> AlsRun.java, GraphingData.java, Idealizer.java, jButtonListenerExample.java .

AlsRun is the main class. I can run the code from within the IDE or by zipping up dist and moving it anywhere and typing: java -jar "Idealizer.jar " (from within "dist").

On the other discussions of this problem it seemed that MANIFEST.MF was implicated. MANIFEST.MF appears correct:

Manifest-Version: 1.0
Ant-Version: Apache Ant 1.8.3
Created-By: 1.6.0_35-b10-428-11M3811 (Apple Inc.)
Class-Path: 
X-COMMENT: Main-Class will be added automatically by build
Main-Class: components.AlsRun

I believe that the following are two big hints.

Big Hint 1 :

When I run the code from the command line the program takes over and the program name that appears on the screen is "components.AlsRun" . When I attempt to launch it by double clicking (from the finder) a program is launched and the name that appears is "AlsRun". The program that is launched in the latter case does nothing and I can only kill it from within "force quit".

Big Hint 2 :

After writing the last sentence I asked myself how to kill it from the command line. If I ran the program by double clicking and then ran ps -A | grep java ps -A | grep java it returned the following:

33383 ?? 0:00.84 /Library/Internet Plug-ins/JavaAppletPlugin.plugin/Contents/Home/bin/java

- jar /Users/pearson/NetBeansProjects/Idealizer/dist/Idealizer.jar

When I run the program from the command line and then do ps -A | grep java ps -A | grep java it returns

33394 ttys001    0:01.46 /usr/bin/java -jar Idealizer.jar

It runs different versions of java depending on if I launch it by double clicking or the command line.

Apparently NetBeans thinks I am creating an "Applet" which is different than an Application?

I am at a loss here. The shortest version of the code that produces the error for me is:

package components; 
import javax.swing.JFileChooser;

public class AlsRun {

public static void main(String[] args) {

    JFileChooser fc = new JFileChooser();
    int returnVal = fc.showOpenDialog(null);        

    };
}

Answer 1

Following the instructions here: http://www.oracle.com/technetwork/articles/javase/javatomac3-137430.html

fixed the problem.
